Hello team,

Recently, I found my bike getting pretty juddery in the front.
It still soaks up bumps (depressions) well, but humps (raised areas and corrugations) feel like I'm going to be thrown off the bike after a while.

I have Hyperpro springs, with the supplied oil (Don't quote me but I think it was 10W), half in each leg which I weighed exactly.

Forks are dropped 10mm through the yoke, and I have 20mm bar risers now.

They have done some mileage, I'm going to guess at around 18,000 miles.


I've experimented with pre-load. Currently the adjusters were wound all the way out to flush, and then 6 turns back in.

I'm thinking of changing to a heavier oil, would this be the way to solve the damping issue?
Or maybe I've set my pre-load too high?
I do like stiff suspension, but this has gotten a little dangerous, I feel.

I read that when changing the fork oil, I should be checking the height of the oil in the forks, obviously with the new springs this is different to stock, so I'm assuming it's just 500ml in each.

I realise suspension is personal preference, but any input would be much appreciated.

Regards,
Steve.
